• One ticket, two museums: admission also covers the Deutsches Technikmuseum on Trebbiner Straße on the same booked date
• No backpacks inside: large bags aren't allowed in Spectrum, so use the lockers (they can't take big luggage)
• Under-10s stay with an adult: children under 10 can't explore on their own, and school groups have booked slots Tuesday to Friday from 9am to 1pm

Science Center Spectrum is the hands-on wing of the Deutsches Technikmuseum, a building of more than 150 experiment stations that visitors are meant to touch and test. Kids light up a plasma tube, set a Newton's cradle clacking and cast colored shadows on the wall.

The stations are grouped by theme: light and vision, electricity and magnetism, heat, force and energy, mechanics and motion, and music and sound.
